The invention relates to devices for remov ing insulation fromwire and otherarticles, it being particularly directed to devices for the removal of insulating enamel from wire.

rlhe object of the invention is to provide a simple device by which insulation may be rapidly and eihclently removed from wire.

Another object is to provide a device fior-r removing insulation from wire withmeans by which to sever the wire or wires. e

The invention consists of ofpositely reciprocating abrading surfaces etween whlch the insulated wire is disposed for removing the insulation and a rotating cutting member. The invention is illustrated in the accompanying drawings, in which i Figure-1 is a plan view of a device embodying the invention; Fi 2 is arear elevational view of the same; Fig. 3 a side elevational view of the device and Fig. 4 a cross sectional view on line 4-4 of Fig. 1.

In the illustrative embodiment of the invention, 1 is a frame upon the base 2 of which an electric motor 3 is mounted. A' worm 4 is secured to the end of the shaft 5 of the motor and meshes with a worm gear 6 secured to a vertical shaft 7 supported in a bearing 8 on the'base 2 and in a bearing 9 formed in the top member 10 of the frame. A transversely or upwardly tapered Y groove 11 is formed in the top member 10 in which two blocks 12 and 13 are longitudinally slidable, the side walls of each block being tapered to correspond to the taper of the walls of the groove. i Between each block and the rear wallof the groove is a block 14 that is engaged by a set screw 15 ,disposed in the top member 10. By tightening up the set screw the block 14 may be moved toward the blocks 12, 13 to take upwear. Between the two blocks 12 and 13 is a cam 16 that is secured to the up er end of the shaft 7. The cam is engaged y the two blocks and it separates theml when it is revolved by the shaft. e

A plate 17 is secured to the block 12 bythe screws 17 andhas an extension 18 at its front edge about which is removably engaged an abrasive medium n19, such as sandpaper or emery cloth, the medium bein held in place by avspring 20 secured to the p ate. Lugs 21, 22 also project from opposite ends of the plate 17 respectively, and are preferably bent downwardly. Springs 23, 24 are connected respectively to the lugs 21, 22 and to similar lugs 25, 26 similarly formed on the opposite ends of the plate27 that is secured by the screws 27il to the block 13.

A bar 28 is secured at one end by the screws 29 to the plate 27 and set screws 29 and 30 are carried by the bar by which tension on the bar is regulated. An abrading medium' 31 is engaged on the outer forward end of the bar 2 8 and is held thereon by the spring 32, the medluln 31 be'ing above the medium 19.

The springs 23 and 24 oppose the separatlng movement of the blocks 12 and 13 and of the plates 17 and 27 by the cam and hence retract the same after each Separating reciprocation.

By adjusting the screws 29 and 30 the clearance between the two abrading mediums is regulated.

A gear 33 isv secured to the shaft 7 and meshes with a gear 34 securedto a horizontal` shaft 35 having abearing 36 on the main y plate 37 secured to the lateral frame and in a extensions 38 o the frame. A cutting blade 39 is mounted on the shaft' adjacent to the wall 37 and a plate 40 is mounted on the opposite side of the blade to form a guard. A. sprlng 41 abuts the hub 42 of the blade at one end and at its opposite end it abuts a kwasher 41El that abuts the :frame 1. On the opposite side of the frame is a washer 43 that abuts a radial thrust bearing 43 carried b the frame. Behind washer 43 are two loc nuts 44 that are threaded on the shaft. By adjusting the lock nuts the desired pressure may be placed on the blade 39 and the arts connected thereto by the expansion o the compressed spiral spring 41.

j A notch 45 is formed in the front edge of the plate 37 into which a wire or wires mayv be inserted to sever them or cut oi an undesirable end thereof.

In vpractice the wire is grasped in both j A two plates slidably mounted one above-the theelectric motor by a foot switch 46 of suitable type that is interposed in the circuit 47 lea ing to the motor, permitting the functioning of themachine only at desiredintervals, thus prolonging the "life of the two abrading mediums 31 and 19.`

What I claim is: 1. An insulation remover lconsistmg of rocable abradin mediums, a revoluble sha t,

means to rotate t e shaft, means driven by the shaft for reciprocating the abrading mediums in opposite directions, means to adjust the mediums relativel to each other, a cutting member having riven connection with on the lateral members andv opposing one anthe shaft and means to place pressure upon the cutting member.

3. The combination of two reciprocable members, lateral members carried by the reciprocable members, abrading mediums on the lateral members and opposing one another, a revoluble shaft, a cam on the shaft engaging both reciprocable members and adapted to reciprocate them in opposite direct1ons, means to retract the reciprocable members and means, to adjust the mediums 35 relatively to each other. c

4. The combination of two alined reciprocable members, lateral members carried by the reciprocable members, abrading mediums other, a revoluble member between the op posed ends of the reciprocable members and adapted to reciprocate the latter members in opposite directions and means to retract the reciprocable members.

In witness whereof I have hereunto signed my name this 23rd day of July, 1926.

EDWARD SNYDER.
